⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on the brake system.
•Allow the vehicle to cool before touching the brake components to avoid burns.

Symptoms

•Brake warning light illuminated on the dashboard
•Vehicle pulling to one side while driving
•Excessive heat from the wheel area
•Unusual noise when braking (e.g., grinding or squeaking)
•Reduced braking performance
•Uneven tire wear on the affected wheel

Diagnostic Steps

1
Inspect the brake caliper visually for any signs of physical damage or corrosion.
2
Check the brake fluid level in the reservoir and inspect for leaks in the brake lines.
3
Remove the wheel to gain access to the brake caliper and rotor.
4
Test the caliper actuator functionality by applying and releasing the brake pedal to see if the caliper moves freely.
5
Use a brake caliper tool to check if the piston can be retracted easily.
6
Inspect the brake pads for uneven wear or contamination.

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and implement safety measures (e.g., using wheel chocks).
Disconnect the vehicle battery for safety.

2. Remove the Wheel

Tools Required: Socket set, torque wrench
Sub-steps:
1. Loosen the lug nuts slightly while the vehicle is on the ground.
2. Lift the vehicle using a jack and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Remove and Inspect the Brake Caliper

Tools Required: Socket set, brake caliper tool
Sub-steps:
1. Remove the caliper bolts with the socket set.
2. Carefully slide the caliper off the rotor and suspend it using a bungee cord to avoid straining the brake line.
3. Inspect the caliper for sticking points, debris, or damage.

4. Service or Replace the Caliper

Tools Required: Brake cleaner, new caliper (if necessary), brake fluid
Sub-steps:
1. If the caliper is serviceable, clean the piston and housing with brake cleaner.
2. Lubricate the piston seals with clean brake fluid.
3. If the caliper is damaged or unable to retract, replace it with a new one.
4. Install the new or serviced caliper by aligning it with the rotor and bolting it in place to manufacturer specifications.

5. Reassemble and Test

Tools Required: Torque wrench
Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle and tighten the lug nuts to the manufacturer’s torque specifications.
3. Reconnect the battery and check brake fluid levels, topping off as necessary.
4. Pump the brake pedal to ensure proper caliper engagement and check for leaks.
